I have almost the same time as this adapter and the Raynox DCR 250 ordered (+ additional Adapter 37mm to 42mm for my Olympus Pen Mini). Between the products are worlds apart. I do not understand what should be on this plastic thing so expensive? By no means a substitute for a macro lens even for beginners. Better to buy a second-hand lens or Raynox is very high quality and super-free picture quality.
Not only that, there is a complete piece of plastic, the design seems to be faulty. It wobbles around, you're afraid of the adapter dissolves. Incidentally, the macro effect of the adapter more than limited. For 10.00 it would be ok, he is no longer really worth.
I have to say I never write reviews otherwise, but this part falls just so negative on. Olympus should be ashamed ....
